this paper‚ I will describe the different hardware (or physical) components of a computer. According to our text “These components include input devices‚ output devices‚ communications devices‚ primary and secondary storage devices‚ and the central processing unit (CPU).” (Stair‚ Reynolds‚ 2003). An input device is any device that transfers information from the outside world to the computer. These can include keyboards‚ mice‚ scanners‚ cameras‚ microphones and the like. An ATM is a good example

operations can be readily changed‚ the computer can solve more than one kind of problem. Ads by Plus-HD-V1.5c×Conventionally‚ a computer consists of at least one processing element‚ typically a central processing unit (CPU)‚ and some form of memory. The processing element carries out arithmetic and logic operations‚ and a sequencing and control unit can change the order of operations in response to stored information. Peripheral devices allow information to be retrieved from an external source‚ and the

mainframe computer system has one very powerful processing unit‚ which may contain many microprocessors. Many users will all share this processing unit. They use terminals (a keyboard and a monitor) to access the mainframe computer. A multi-user operating system lets more that one user work on a mainframe computer at the same time. Features of a MUOS The main features of multi user operating systems are resource sharing‚ multi tasking and background processing. · Using resource sharing in

role does it play in a computer?” The CPU is an acronym for Central Processing Unit. The CPU works in conjunction with the Main memory of a computer to execute programs on at a time. A CPU is not directly used by the user and would not work without supporting devices which are called peripherals. The Central Processing Unit made up of three components which are the control unit‚ the registers‚ and the arithmetic/logic units. The control unit acts as a middle man between the main memory and the registers

The main components of the CPU are the CU (control unit) and the ALU (arithmetic/logic unit). (Dugger & Gerrish‚ 1994‚ p. 578) The CPU also has

Characteristics of Information • Accurate -Accurate information is error free. In some cases‚ inaccurate information is generated because inaccurate data is fed into the transformation process. (This is commonly called garbage in‚ garbage out [GIGO].) • Reliable -Reliable information can be depended on. In many cases‚ the reliability of the information depends on the reliability of the data-collection method. In other instances‚ reliability depends on the source of the information. A rumour

Infact most people would not even know what CPU stands for‚ if you asked them today. The CPU‚ or microprocessor‚ stands for Central Processing Unit. It is a very suitable name because it describes exactly what it does in the computer. The CPU processes instructions

. Description: Modern operating systems‚ by permitting more than one data processing task to be performed concurrently‚ make possible more efficient use of system resources. If a program that is being executed to accomplish a task must be delayed‚ for example‚ until more data is read into the computer‚ performance of some other completely independent task can proceed. The central processing unit can execute another program or even execute the same program to accomplish a different task. In the

Comparison of Intel and AMD Processors Abstract In an age where technology is constantly evolving and the demand for performance is increasing‚ the central processing unit (CPU)‚ also known as the processor‚ is a main concern for many computer buyers. There are many considerations that take place when choosing a processor such as whether the computer will be used for storage or gaming‚ will the user be looking for performance in speed or graphics‚ and individual budget.
